To obtain favorable ratings for their apps, developers often present rating screens to users who are believed to like the app. Further, to suppress poor ratings, some app-developers neglect to send every rating to the app store. Thus app-ratings are affected by selection bias and by preferential reporting.

This disclosure uses the facility of rewarded ads to present a ratings form to the app user. Both ad and its embedded ratings form are controlled by the app store, such that users are selected with lower statistical bias. Free-form textual reviews can be included such that the app store passes these as feedback to the publisher. Ratings and reviews are reported to the app store regardless of their level or sentiment.
